Description

Exhaust structure

Technical Field

The utility model belongs to the technical field of exhaust, especially indicate an exhaust structure.

Background

The exhaust port structure of the drying apparatus has important influence on the environment in consideration of the performance of the drying apparatus. As an indispensable part of the drying equipment, the design of the exhaust port directly affects the recycling of volatile components and the workload of subsequent separation equipment. Therefore, the design of the exhaust port is very important. The gas vent that adopts at present is mostly the straight cylinder type, this kind of gas vent simple structure, and convenient to use, but has not few problems, especially when volatile gas-liquid smugglies seriously, seriously influences volatile purity, brings very big work load for back splitter simultaneously.

fig. 2 is a schematic perspective view of the inner sleeve of fig. 1.

In the figure: 1. an exhaust funnel; 11. an exhaust port; 12. an air inlet channel; 2. a dome; 3. an inner sleeve; 4. a first flange plate; 5. the outer wall of the inner sleeve; 6. a baffle plate; 7. a second flange.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1: an exhaust structure comprising: exhaust funnel 1, calotte 2 and endotheca 3, exhaust funnel 1 is T type structure, T type structure includes gas vent 11 and intake duct 12, endotheca 3 is located in intake duct 12, be connected with a plurality of downward sloping 20-60 baffles 6 on the inner wall of 3 lower parts of endotheca, a plurality of baffles 6 divide two to be located on the inner wall relatively, two adjacent baffles 6 dislocation set each other and certain distance apart make 3 interior formation snakelike passageway of endotheca, the bottom of intake duct 12 is the air inlet, the top is connected with calotte 2.

The utility model is suitable for an any exhaust device that needs, be particularly suitable for drying device, when it is connected the use with drying device, volatile gas in the drying device gets into endotheca 3 from the air inlet of intake duct 12 bottom, a plurality of baffles 6 that set up on 3 inner walls of endotheca play the vortex effect, it makes the volatile flow state change, the volatile finally advances along serpentine channel and discharges via gas vent 11, at the continuous in-process that strikes baffle 6, the material smugglied secretly in the gas is intercepted on baffle 6 surface by baffle 6, baffle 6 slopes to set up, the material of adhesion on baffle 6 can flow back under the action of gravity.

The utility model discloses a plurality of baffles interact, are showing and have been restraining the gas-liquid and smuggleing the phenomenon secretly for the gas purity that volatilizees can improve, has improved drying equipment output simultaneously, has reduced back splitter work load, prolongs after-treatment equipment's life. And, the utility model discloses simple structure, installation are simple, and the gas tightness is good and the operation is reliable and stable, has played energy saving and emission reduction's effect to a certain extent.
